我有一个自定义视图,看起来像这样:
<LinearLayout
android:orientation="vertical">
<TextInputLayout>
<TextInputEditText />
</TextInputLayout>
<TextView
android:text="Some info text" />
</LinearLayout>
基本上是带提示的普通编辑文本,其下面带有“信息”文本。
当我尝试在自定义视图上requestFocus()
时出现问题。它将光标正确地放置在编辑文本中,但仅滚动到编辑文本的底部。因此,“信息”文本将被“隐藏”,直到用户向下滚动一点。
是否可以告诉自定义视图其“焦点区域”是什么?也许是另一种使系统正确滚动的机制(即滚动到“信息”文本的底部?
任何帮助将不胜感激。谢谢。

调用此方法并传递EditText和ScrollView的变量,
from __future__ import absolute_import
from __future__ import division
from __future__ import print_function
from multiprocessing import Process
import cv2
#from scipy.stats import math
import datetime
count = 0
def saving_frame(frame):
count = 0
date_string = datetime.datetime.now().strftime("%Y-%m-%d-%H:%M")
count = count +1
cv2.imwrite('Frame_'+str(count)+date_string+'.png',frame)
return
def runInParallel(*fns):
proc = []
for fn in fns:
p = Process(target=fn)
p.start()
proc.append(p)
for p in proc:
p.join()
video_capture_1 = cv2.VideoCapture(0)
video_capture_2 = cv2.VideoCapture(1)
video_capture_3 = cv2.VideoCapture(2)
print ('Start Rec')
while True:
ret_1, frame_1 = video_capture_1.read()
ret_2, frame_2 = video_capture_2.read()
ret_3, frame_3 = video_capture_3.read()
runInParallel(saving_frame(frame_1),saving_frame(frame_2),saving_frame(frame_3))
cv2.imshow('frame1', frame_1)
cv2.imshow('frame2', frame_2)
cv2.imshow('frame3', frame_3)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
video_capture_1.release()
video_capture_2.release()
video_capture_3.release()
cv2.destroyAllWindows()
完成
